2. General description of the HygroLog HL-NT
2.1 Models
Basic models without display and keypad

be ordered separately). Probe model HC2-S can be mounted either internally or in the
extended position. Other probe models are external and require an extension cable.
o HygroLog HL-NT3: same as HL-NT2 with 2 additional connectors suitable for a
HygroClip 2 digital probe.
Models with display and keypad
o HygroLog HL-NT2-D: same probe as HygroLog HL-NT2

o Models HL-NT2-P, HL-NT2-DP, HL-NT3-P and HL-NT3-DP are supplied with an internal
HC2-S probe pre-installed.
2.2 Required accessories
● Models without display/keypad:
The following accessories are required in order to be able to use the logger:
- Any model of docking station (except model DS-NT1)
- Connecting cable docking station to PC
- PC with the ROTRONIC HW4 software installed (version 2.3.0 or higher)
● Models with display/keypad:
In principle, these models can be used without any accessory. However, accessing all of the
product functions and changing some important settings such as the date and time requires the
same accessories as for the models without display.
2.3 HygroLog HL-NT inputs
2.3.1 Probe input 1
HygroLog HL-NT2-P, HL-NT2-DP, HL-NT3-P and HL-NT3-DP: these models are supplied with
an internal HC2-S plug-in probe. This probe can be either retracted or extended. The probe can
also be separated from the logger with an extension cable, and in this case the HC2-S probe may
be replaced with another model of HygroClip 2 probe so as to meet specific application
